I am confused... my police dept fire and ems are not showing ANY pl or dpl!! they are on a repeater, i think, 458.0375 and 453.0375 i can hear them better on 453.0375 and kinda crapy on 458.0375. anyways they dont show a pl or dpl! they have four channels... and none of them do. they both sound the same, so... help! i hear about people programming pl tones to mute when the repeater turns off! how do i? someone told me they might be on csq. is that bad?
